Bag Cosmetic Container With Protective Pipe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid cosmetic containers face issues where the application body can be deformed or broken under external pressure, and the bag-like container's self-restoring force is insufficient to fully dispense the cosmetic, leading to remaining product and protection concerns.
Innovation Solution
A liquid cosmetic container design featuring a bag-like container with a pipe portion extending to the bottom and a slit opening, allowing the application body to be protected and ensuring efficient dispensing of the cosmetic through the pipe, reducing waste and enhancing protection against external pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the bag-like container is made soft for pushing and squeezing to reduce remaining cosmetic, then the cosmetic can be dispensed more completely, but the application body is deformed or broken under external pressure
Solution Approach 1:
The patent places the application body inside a protective pipe portion that is nested within the bag-like container structure. The pipe portion acts as an inner container for the application body, providing mechanical protection while allowing the outer bag to remain soft and squeezable for complete cosmetic dispensing.
Solution Approach 2:
The pipe portion serves as an intermediary structure between the soft bag-like container and the application body. It mediates the mechanical stress by absorbing external pressure away from the application body, allowing the bag to be squeezed for complete dispensing without transmitting damaging forces to the application body.
2Reliability
If the bag-like container is made hard to protect the application body, then the application body is protected from deformation, but the self restoring force is insufficient to dispense the cosmetic completely
Solution Approach 1:
The protective function is nested within the pipe portion structure rather than making the entire container hard. The pipe portion provides localized protection to the application body while the outer bag-like container remains soft and squeezable, enabling complete cosmetic dispensing through user action.
Solution Approach 2:
The patent applies different mechanical properties to different parts of the container: the pipe portion containing the application body has rigid protective properties, while the bag-like container portion has soft, flexible properties for squeezability. This local differentiation resolves the contradiction between protection and dispensing efficiency.
3Device complexity
If the application body goes directly into the bag portion, then the structure is simple, but the application body is exposed to external pressure and may be deformed or broken
Solution Approach 1:
The patent introduces a nested structure where the application body is placed inside the pipe portion, which is itself inside the bag-like container. This nested arrangement adds minimal structural complexity while providing substantial protection to the application body against external pressure.
Solution Approach 2:
The container is segmented into distinct functional portions: the bag-like container for holding cosmetic, the pipe portion for protecting the application body, and the lid portion for closure. This segmentation allows each component to perform its specific function optimally with minimal overall complexity.

AI summary
The invention protects an application body as well as reducing a remaining amount of a liquid cosmetic. A bag-like container accommodates liquid cosmetic therein and provides an opening neck portion to communicate the inner side and the outer side thereof, a pipe portion in the opening neck portion extends to the bag portion bottom side. The pipe portion peripheral surface has an opening for the liquid cosmetic going into an internal portion. An application body in a lid portion goes into the pipe portion by installing the lid portion to the opening neck portion to reach the opening position. If a user pushes and squeezes the bag portion, the liquid cosmetic goes into the pipe portion through the opening, the application body dips into the liquid cosmetic to run short of the liquid cosmetic and to protect the application body by the pipe.
